ARM: perf: save/restore pmu registers in pm notifier This adds core support for saving and restoring CPU PMU registers for suspend/resume support i.e. deeper C-states in cpuidle terms. This patch adds support only to ARMv7 PMU registers save/restore. It needs to be extended to xscale and ARMv6 if needed. Signed-off-by: Sudeep KarkadaNagesha <sudeep.karkadanagesha@arm.com>
